You may be able to do it through the BIOS or by using a jumper.

But a sure-fire way to clear CMOS is to remove your PC's battery.

Turn the PC off and look for the battery.

The battery is mounted on the motherboard and looks like a coin. You can pry it out.

Leave it out for a half hour and then put it back in.

A half hour ????? A half hour ???? 10 seconds is all it needs.

On the motherboard, usually near the cmos battery ( looks like a nickle ) there are 3 jumper pins. Two of them are connected by a small plastic cap. Move the cap to cover the other 2 jumper pins for 10 -12 seconds. Then put it back where it was. Reboot the computer and go back into the BIOS. You will have to reset the date and maybe a few other settings.

Some new boards such as my XFX board let you push a button on the input plate.

I would replace the battery with a new one when you take it out, they are not expensive and you can but them anywhere they sell batteries for earphones etc.

I have a Gigabyte MB and there are only 2 pins, and no jumper cap.
I use a screwdriver to clear cmos.

Assuming your MB is the one listed in your specs yours works the same way as mine.

Here is link to your MB manual:
GIGABYTE - Motherboard - Socket AM3 - GA-M68MT-S2 (rev. 1.3)

this is from the manual:

10) CLR_CMOS (Clearing CMOS Jumper)
Use this jumper to clear the CMOS values (e.g.date information and BIOS configurations) and reset
the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few seconds.
